" APPARATUS FOR DISGHABG-ING LIQUID.

Application filed December 6, 1920. Serial No. 428,697.

has for its object to provide an automatically operated apparatus adapted to discharge or release volumes of liquidat periodic intervals.

Another object of my invention is to provide an apparatus of the character described which will be positive and durable in operation and simple and economical in construction. .7

Another object of my invention is to provide an apparatus more: compact andconvenient than are the devices heretofore uti lized in the art to effect a similar result.

The invention will be readily understood from the following description of the accompanying drawings, in which I have illustrated my invention as embodied in a sewer fiusher. 1

Figure 1 is a vertical section illustrating the apparatus as positioned within the well of a sewer system. f

Fig. 2 is a top plan view of the same with the cover for the well removed.

Fig. 3 is a top plan view of the guide bearing preferably utilizedwith the apparatus illustrated in Figs. land 2.

Fig. 413 a vertical section of the guide bearing. taken on the line 4+4 of Fig. 3..

Fig. 5 is a perspective view of the actuat ing bucket utilized with the apparatus illustrated in Figs. 1 and 2.

Referring to the drawings A illustrates a well of any particular design communicating at its bottom with a pit B. The pit B communicates with a sewer conduit C. The well A is provided with a manhole cover D.

A partition E is mounted within the well. A and separates the well A and the pit B. The partition E is formed with a port F provided with valve seat 1.

A hanger 2 depends from and is supported by the under side of the partition E. The hanger 2 provides a fulcrum for a lever arm 3 pivotally supported intermediate its ends by the hanger 2. The arm 3 is conthe rod 10.

nected at one end to an actuating bucket 4 through a link 5.

The bucket 4 is pivotally supported at its upper end by a bracket 6 depending from' the partition E. The bottom 7 of the bucket 4 is inclined to provide a contracted port 8. A cover 9 extends over the lower end of the bucket A.

PatentedJiily 1a, 1921.

A rod 10 is hingedlyisupportedat the upper end of the arm 3 and extends through the port F to a distance within the well A.

The rod. 10 is screw threaded at its upper end to receive and support a bell-shaped welghted valve 11. The valvell is pro;- vlded with a beveled ring 12 at its lower end to seat on the valve seat 1.

The. rod 10 is slidably confined within an antifriction guide 13 mounted within the valve 11 by means of a plurality of legs lasupported by the partition E. The aperture 15 through the guide13 as illustrated in Flg. 4 1s 7, provlded with a downwardly and outwardly slanting wall 16 to insure against the guide 13 biting or gripping I The opposite wall 17 of the guide 11 is also slanted downwardly and outwardly to reduce the frictional contact along the rod 10. There is thus provided a one point anti-friction guide for the rod 10. The aperture 15 between the walls 16 and 17 has a greater diameter than: the rod 10 to allow a play for the latter. i

The guide 18 will insure that in operation the valve 11 properly find the valve seat 1.

In operation water is introduced to the well A through a pipe 6 at any pie-determined rate. When the water levelreaches the top of a stand pipeH the water will.

flow down the pipe H and pass into the actuating bucket 4:. The hanger 2, arm 3, bucket 4., link 5, and bracket 6 provide a compound lever for raising the valve 11 and releasing the water in the well A.

So long as the relative force derived from the weight of the valve 11 is greater than the relative force derived from the weight of the water within the bucket 4, the valve 11 will remain seated. lVhen a suflicient amount of water has passed through the pipe H into the bucket A to over-balance the weight of the valve 11 the bucket 4 will tend to drop downwardly, thereby raisin the valve 11 05 its seat 1 and cracking the valve. Upon the lowering of the bucket 4 the volume of water confined at the upper and deeperportion thereof will pass toward the port 18. This will increase the effective 7 lifting force of the weight of the water with in the bucket as it will increase the length of the effective distance between the fulcrum of the bucket and the water. Thereby anytendency-of the valve 11 to remain bal:

'anced at the eracking point will be overcome and the valve ll will be hoisted asufficient distance off its seatl to permit the waterwithin-the well A to pass downward in quantity, thus .efi'ectively flushing. theI sewer C. The cover 9 and'r'elatively narrow port 8 necessitate thatthewater within the bucket A drain out slowly, thus maintaining. the valve llopen until the well A has been thoroughly drained.

, A decided advantage of the above construction is thate rcept for the valve 11 the I actuating parts are all below (the partition: E. In prior'devices of 'thisch'araoter it has i been necessary to provide walking beams or the like above the/partition E. This has rendered itinconvenient for a man to enter" thewell A andfhas resulted in frequent [de rangement of theapparatus by one entering the well. The compound lever arrangement utilized inmy: construction renders it possible'to' position: the apparatus below the purpose offexample only. My-invention is V not confined to the precise proport-ionor ar rangement' of parts above set forth and contemplates such deviations therefrom as are withinthe scope or the following claims.
